XmlWriter.WriteCharEntityAsync(Char) XmlWriter.WriteCharEntityAsync(Char) XmlWriter.WriteCharEntityAsync(Char) XmlWriter.WriteCharEntityAsync(Char) Method

定義

以非同步的方式強制產生指定的 Unicode 字元值的字元實體。Asynchronously forces the generation of a character entity for the specified Unicode character value.

public:
 virtual System::Threading::Tasks::Task ^ WriteCharEntityAsync(char ch);
public virtual System.Threading.Tasks.Task WriteCharEntityAsync (char ch);
abstract member WriteCharEntityAsync : char -> System.Threading.Tasks.Task
override this.WriteCharEntityAsync : char -> System.Threading.Tasks.Task
Public Overridable Function WriteCharEntityAsync (ch As Char) As Task

參數

ch
Char Char Char Char

要產生字元實體的 Unicode 字元。The Unicode character for which to generate a character entity.

傳回

表示非同步 WriteCharEntity 作業的工作。The task that represents the asynchronous WriteCharEntity operation.

例外狀況

在先前的非同步作業完成前呼叫了 XmlWriter 方法。An XmlWriter method was called before a previous asynchronous operation finished. 在此情況下,會擲回 InvalidOperationException 與「非同步作業已經在進行中」的訊息。In this case, InvalidOperationException is thrown with the message "An asynchronous operation is already in progress."

-或--or-

在未將 Async 旗標設為 true的情況下呼叫了 XmlWriter 非同步方法。An XmlWriter asynchronous method was called without setting the Async flag to true. 在此情況下,就會擲回 InvalidOperationException 並顯示訊息「如果您要使用非同步方法,請將 XmlWriterSettings.Async 設為 true」。In this case, InvalidOperationException is thrown with the message "Set XmlWriterSettings.Async to true if you want to use Async Methods."

備註

這是非同步的WriteCharEntity,使用相同的功能。This is the asynchronous version of WriteCharEntity, with the same functionality. 若要使用此方法,您必須設定Async旗標設為trueTo use this method, you must set the Async flag to true.
